Biodegradable Fire Suppressant Composition for Environmental Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire suppression methods are often non-environmentally friendly, corrosive, and ineffective in rapidly extinguishing fires, particularly in large or hard-to-reach areas, and may pose risks to humans and structures due to water damage and reignition concerns.
Innovation Solution
A biodegradable, non-toxic fire suppressant composed of clay, nitrogen compounds (urea, ammonium sulphate, and ammonium polyphosphates) that forms a barrier, absorbs heat, and displaces oxygen, creating a chemical endothermic reaction to rapidly lower temperatures and prevent combustion, usable in various fire types without causing harm to humans or structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fire suppressants are used to remove oxygen and create barriers, then fire suppression effectiveness is improved, but environmental harm and corrosion increase
Solution Approach 1:
The invention changes the chemical composition parameters of fire suppressants by using biodegradable alternatives such as gelatin, starch, or cellulose derivatives instead of traditional harmful chemicals. This maintains fire suppression effectiveness while eliminating environmental harm and corrosion issues.
Solution Approach 2:
The invention uses composite materials combining biodegradable polymers (gelatin, starch, cellulose) with fire-retardant agents. This creates a multi-functional material that provides both fire suppression and environmental safety, resolving the contradiction between effectiveness and environmental harm.
2Temperature
If large amounts of water are used for fire suppression, then cooling effect is improved, but water damage to structures increases
Solution Approach 1:
The invention changes the physical state and composition of the suppressant by using gelatin-based gels or starch derivatives that retain moisture in a gel structure. This provides sustained cooling effect without the excessive water application that causes structural damage.
Solution Approach 2:
The biodegradable polymer-based suppressants provide continuous cooling and fire suppression action as they slowly release moisture and form protective char layers. This continuous action maintains temperature control without requiring large volumes of water that would damage structures.
3Duration of action of moving object
If conventional fire retardants are applied to prevent reignition, then fire suppression duration is improved, but toxicity and environmental persistence worsen
Solution Approach 1:
The invention changes the chemical nature of fire retardants from persistent synthetic chemicals to biodegradable natural polymers like gelatin, starch, and cellulose. These materials maintain fire suppression effectiveness over extended periods while naturally decomposing, eliminating toxicity and environmental persistence issues.
Solution Approach 2:
The biodegradable suppressant materials are designed to be temporarily effective during and after fire suppression, then naturally decompose through biological processes. This allows the materials to be discarded safely without long-term environmental harm, resolving the contradiction between duration of protection and environmental safety.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively suppresses and prevents fire reignition, reduces firefighting time by two-thirds, is safe for personnel and the environment, and can be applied using existing equipment, minimizing water usage and avoiding structural damage.
Implementation Method 1
The nitrogen compounds will degrade when exposed to high temperatures so the nitrogen will remove the oxygen present in the ambient air, cooling the area. The reaction will also absorb heat, lowering the air temperature dramatically.
Implementation Method 2
The nitrogen compounds will degrade when exposed to high temperatures
Implementation Method 3
This emanation of massive cold in the form of nitrogen (cold gas) not only dramatically lowers the temperature in the surrounding area, but also displaces a large portion of the available oxygen, isolating the fuel, preventing the oxidation of the combustible material.
Implementation Method 4
The clay and the rest of the components will form a barrier that prevents further ignition.

AI summary
A fire suppressant including in weight percent technical urea 10-30%, ammonium sulphate 20-50%, and sodium bentonite 12-26%. The fire suppressant further includes polypropylene glycol (polyglycol), alkyl sulfonic acid, castor oil, guar gum, and/or triethanolamine dodecylbenzene sulfonate. The fire suppressant does not pose any risk to plant or animal life since the product is completely benign and is classified as non-toxic. It does not cause any damage to aquifers or groundwater, and it biodegrades in 30 to 60 days.
